Title: PrestaShop Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) Vulnerability
Overview:

PrestaShop is an Open Source e-commerce web application. Prior to versions 8.0.4 and 1.7.8.9 the ValidateCore::isCleanHTML() method of Prestashop misses hijackable events which can lead to cross-site scripting (XSS) injection allowed by the presence of pre-setup keyframes methods. This XSS which hijacks HTML attributes can be triggered without any interaction by the visitor/administrator which makes it as dangerous as a trivial XSS attack. Contrary to other attacks which target HTML attributes and are triggered without user interaction (such as onload / onerror which suffer from a very limited scope) this one can hijack every HTML element which increases the danger due to a complete HTML elements scope. Versions 8.0.4 and 1.7.8.9 contain a fix for this issue.
